One compact microstrip low-pass filter using conventional elliptical headed dumbbell shaped

In this paper, we report a design of high sensitivity Photonic Crystal Fiber (PCF) sensor with high birefringence and low confinement losses for liquid analyte sensing applications. The proposed PCF structures are designed with supplementary elliptical air holes in the core region vertically-shaped V-PCF and horizontally-shaped H-PCF. The full vectorial Finite Element Method (FEM) simulations p...

Underestimation of coronary arterial stenosis at clinical arteriography has been explained by inadequate radiological views of crescentic or slit-shaped lumens. Postmortem perfusion-fixation of the coronary arteries at physiological pressures shows that most stenotic lesions result in circular, elliptical, or D-shaped lumens. Crescentic lumens in fully distended vessels are associated only with...

A growing body of observational evidence suggests that the luminosity, pho-tometric shape and amount of rotational or anisotropical support in elliptical galaxies may provide vital clues to how they formed. Elliptical galaxies appear to fall into two distinct categories based on these parameters: bright, boxy shaped, with little or no rotation, and less luminous, disky shaped with significant r...

A growing body of observational evidence suggests that the luminosity, photometric shape, and amount of rotational or anisotropic support in elliptical galaxies may provide vital clues to how they formed. Elliptical galaxies appear to fall into two distinct categories based on these parameters: bright, boxy-shaped, and having little or no rotation, and less luminous, disky-shaped, and having si...

We study the influence of particle shape on the shear band formation in quasistatic granular media in biaxial compression test using two-dimensional Distinct Element Method (DEM). Elliptical-shaped particles are used to study the influence of particle shape. We also report an experimental verification to check the ability of DEM to model elliptical particles created by the clustering technique....

A D-shaped elliptical hollow core fiber surface plasmon resonance (SPR) sensor is proposed and analyzed here using gold titanium oxide (TiO 2 ) layer. The geometry consists of a doped with concentric central air hole. finite element method-based simulation software COMSOL Multiphysics used for numerical analysis. Both TiO layers are optimized. responds over wide range refractive index (RI) from...
